. The object of my invention is to provide a reversible drum of simple,durable and inexpensive construction, which may be utilized foroperating various kinds of cable con- I trolled devices such as dragline buckets, clam shell and hoisting devices, the drum also beingparticularly adapted for operating the dipper stick of an excavatingbucket.

A further object is to provide a reversible m drum which is providedwith a suitable driving mechanism designed to be o rated in a continuousmanner and in one direction, and to. provide in connec-' tion therewithmeans whereby the cable drum may be operatedin unison with said drivingmechanism, or may be operated in 'a reverse direction at a higher speedthan'the said driving device.

A further Afurther object is to provide in connection with a reversiblecable drum, improved 80 means for throwing the drum intooperativerelation with a driving element, said device being providedwitha' manually controlled clutching mechanism and a power clutchingmechanism so arranged that the power clutchfully set forth, pointed outin my claims, and

Figure 6 is a detail sectional view taken von 5 theline 66 of Figure 3,showing the manner in which the reversing mechanism is thrown out ofgear; and- Y Figure 7 is a on the line 77 of Figure 1.

Referring to the drawings, I have used the reference numeral 10 toindicate frame members on which my device is mounted, said frame membersbeing provided preferably with inwardly projecting brackets 11. Each ofthe brackets 11 is provided with a detachable block 12 in which ismounted a detail sectional view taken horizontally arranged, shaft 13,said shaft being fixed in said blocks by means of suit-I able set screws14 so as to support the shaft rigidly therein.

Rotatively mounted on one end of the shaft 13 is a driving gear 15,whichis designed-to trated in Figure 3.. The gear 15 is provided with ahub 16, on which is rotatively mounted a collar 17, the collar beingprovided with an annular groove 18 in which are mounted of the members19 are provided with'outwardly extending flan es-20 and '21, the flanges21 being tfonsiderably longer than the anges 20.' e flanges 20 areprovided with a screw 22, while the flanges 21' are. mounted within abracket 23; said bracket comprising a pair of spaced,vertical1y-arrangedmembers having their upper ends of the frame mem rs10. I r l I'Mountedbetween the vertical members. of the bracket 23 is a cam 26,said cam being designed to'en'ga'ge oneofthe members 21,' the oppositemember 21 being designed to rest against ase'tscrew 27. he cam 26 isprovided with a horizontally extending arm- 28, to which an operatinglink 29 is pivotally nnectedi The members '19 are ad usted in such amanner by means of the screws 22' and 55 56 is mounted between the hubof the clutch spring being connected to the spoke 32 of to mesh with thepinions 37, said gear being 27 that the collar 17 will rotate freelywithin the members 19 when the lever 28 is at its upper limit ofmovement, permitting the members 21 to be separated, the said members 19being designed to frictionally grip theicollar 17 when the lever 28 ismoved downwardly, causing'the cam 26 to. elevate the lower one of themembers 21. This pro- Vides means whereby the collar 17 will be slightlyrotated relative to the rotating hub in a manner hereinafter moreclearly set forth.

The collar 17 is provided. with a radially projecting arm 30, the freeend of which is provided with a spring 31, one end of the being designedto carry, a pinion '37. Rotatively and slidably mounted on the hub ofthe spider is a clutchme-mber 38 having its periphery provided with acone-shaped clutching surface. The hub of the member 38 is provided witha spur gear 39 designed rigidly connected tosaid hub.

Supported on the spokes of the gear 15 is an internal gear 40- which isalso in mesh with the pinions 37. Rotatively mounted on the shaft 13 isa cable drum 41 having flanges 42 and 43, the flange 43 being providedwith a clutch member 44 designed to coact with the clutch member 38. Theflange 43 is also provided with a band drum 45 having a clutch band 46,one end of which is secured to a pin 47 projecting inwardly from thegear ,15. The other endof the band 46 is connected to a pin 48, saidpin'being mounted on one end of a lever 49, said lever being pivotallymounted in a bracket 50 secured to one of the spokes of the gear 15. Theinner end of the lever 49 is provided with a roller 51 designed to makeengagement with a cam 52 formed on the collar 17.

The free end of the band 46 isadjustably connected to the pin 48 bymeans of a bolt 53, a spring 54 and a bracket 55. A spring member 38 andthe inner end. of the drum 41 for yieldably moving the clutch member 38out of engagement with the clutch memng the drum 41 len hwise on,theshaft 13. The clutch mem er 44 is her 44'by sli v brou ht intoengagement with the clutch mem er 38 by means of a cam device 57 whichis rotatively-mounted on the shaft 13 and'which is designed to coactwith the sta the lower end of the link 29, the shaft 62 being actuatedby means of a hand lever 64.

A large amount of wear and noise may be eliminated by removing thepinions'37 from their coac ting gears, thus throwing the clutch member38 out of operative relation with the gear 40. The clutch 38 may then bepermitted to rotate with the clutch member 44, or the clutch member" 38may be thrown out of operative relation with the last said clutchmember.

The operation of my device is as follows: Assume-that the drum 41 isprovidedwith a suitable cable having its free ends operatively connectedwith a dipper stick in such a manner that as the drum is rotated in onedirection the dipper stick will be crowded out wardly, and as itis movedin the opposite direction the dipper stick will be moved inwardly. Orthe drum might be provided with a cable adapted to operate a drag bucketor a skimmer bucket, one of the ends of the cable being designed toserve as an out-haul cable, and the other end of the cable as an inhaulcable, and in both cases it will be seen that it is necessary to reversethe rotation of the drum to actuate the buckets. Sometimes it is desiredto disconnect the drum from its operating means to cause the buckets tobe brought to a standstill. v

. Front the foregoing construction it will be seen that if the pinions37 are mounted on the pins 36 and the gear 15' is rotated inacounterclockwise direction, as illustrated in Figure 3, the internalgear 40 will also be rotated, which will cause the pinions 37 to berotated, which in turn .will rotate the gear 39 in the oppositedirection from the internal gear 40 and at a higher speed. This in turnwill cause the clutch member 38 to be rotated in the opposite directionfrom the gear 15.

Then it will be seen that if the lever 64 is to engage-the clutch member38, which will cause the drum 41 to be rotated in the opposite directionfrom the gear 15 and at a higher speed. v.

If the shaft. 62 is operated in a clockwise direction, then the linkwill be elevated and the drum 41 moved axially and the clutch members 38and 44 caused to disengage each other. The link 29 will at the same timebe moved downwardly, causing the cam 26. to

, squeeze the members 21 together, thereby causing the members 19 tofrictionally engage the collar 17, which is being rotated in' unisonwith the gear 15 through the spring 31. This frictional engagementbetween the members 19 and 17 will cause the movement of the collar 17to be retarded relative to the movement of the gear 15, and the cam 52to engage the roller 51 of the arm 49, causing the inner end of said armto be moved outwardly and the outer end of said arm to be moved, so thattension will beapplied to the band 46, which will be brought toengagement with the drum 45, causing the cable drum 41 and the gear 15tobe locked to operate in unison, the drum- 41 rotating at the samespeed and in the same direction as the gear 15.

This provides means whereby powerful clutching action may be impartedbetween the band 46 and the drum with a comparatively small amount ofenergy being imparted to the lever 64, and provides means whereby asmall amount of manual energy is required to operate what I shall termthe power clutch member comprising the band 46, the lever.

49 and the power driven cam 62. The members 19 and '21, together withthe cam 26 and the lever 28, constitute what ,I shall term the 'manuallycontrolled clutch member.

Sometimes it is desirable to operate the drum in one direction only, inwhich case the inions 37 are removed in the manner hereineforedescribed, thereby eliminating the wear: between the said pinions andtheir (50- actin gears, as well as the noise created there y, and alsothe wear between the clutch member 38 and the hub of the spider 35.

Thus it will be seen I have provided a reversible cable drum which isparticularly 3 adapted to be used on that type of an excavating machinehavin a boom on which are mounted the various 'nds of excavatmg buckets,so that the said drum may be ,utilized for-operating the variousdevices, and which is very compact, especially in length, as thestationary spider is mounted within the flange of the clutch member andalso the internal and spur gears, the clutch members for setting thedrum and driving er in fixed relationbeing mounted within the flange ofthe gears.

This compact arrangement is a very desirable feature in a device of thiskind, inasmuch as the width of the entire excavating machine may bematerially thereb decreased, decreasing the cost of the mac 'ne as wella as the weight.

Another advantage of my device consists in being able to easily andquickly throw the'reversing mechanism out of operation when so desired.

Another advantage of the device lies in the easier manner in which thevcontrolling devices may be operated; This is also every desirablefeature, as in eacavating -machmes of this classquite a large number oflever devices have to be operated.

Another advantage of my device lies in roviding means whereby the drummay e operated in a reverse direction at a higher speed than the drivinggear.

from the reverse gears,- it being desirable torake the bucket mat aconsiderablyv higher speed for-the purpose of cutting down the operatingtime as well as imparting momentum to the bucket for throwing it intoopera'tive position and to eliminate the necessity of an extra backline.
